Question

first term and common difference of an a.p are 6 and 3 respectively find t27

Answer 1

Given :-

• First term ( a ) = 6

• Common difference ( d ) = 3

• Number of terms ( n ) = 27

To Find :-

• 27th term of the given A.P

Solution :-

By using A.P formula

★ Aₙ = a + ( n - 1 ) d

⇒ A₂₇ = 6 + ( 27 - 1 ) × 3

⇒ A₂₇ = 6 + 26 × 3

⇒ A₂₇ = 6 + 78

⇒ A₂₇ = 84

27th term of A.P is 84

Answer 2

Step-by-step explanation:

${\red{\underline{\underline{\bold{Given:-}}}}}$

• The first term ( a ) = 6

• Common difference (d) = 3

• The number of terms ( n ) = 27

${\blue{\underline{\underline{\bold{To\:Find:-}}}}}$

• The 27th term of the A.P

${\green{\underline{\underline{\bold{Solution:-}}}}}$

$\tt\pink{Formula \:used}$

$a_{n} = a + (n - 1)d$

Substituting the values :-

$a_{27} = 6 + (27 - 1)3$

$a_{27} = 6 + (26)\times 3$

$a_{27} = 6 + 78$

$a_{27} = 84$

Therefore the 27th term of the AP is 84

$\boxed{ t_{27} = 84}$
